826 Screeching Brakes

Jim Allen · Jul 30, 2009

I redid the right side brakes on my 826 about a year back, mostly to fix a major leak there. I'll get around to the left this fall just because. The old linings weren't all that bad but very oil soaked. All the hard parts looked good as well (they were well lubricated!). Operationally, everything was fine for a long while. Now, those right side brakes have begun to screech badly and they don't seem to hold as well as the other side that hasn't been redone. Obviously. I'll be tearing into it again but I'm wondering if anyone has an idea of what I might expect to see. Many thanks!

I just had my right side brakes apart on my 806 yesterday. The return springs were compressed and packed with brake dust. this wouldnt force the piston back in so it wore the pads out. just take the brakes off but leave the plate with the piston on the tractor, dont bleed fluid out of line either. this way you can see if it is retracted, if its not then look at the springs and see if they are broke or stuck. also check the adjusters to make sure they arnt bottomed out. if all is ok there, then lookat the piston assembly. if its pushed out, try to push back in, crack open bleeder to help relieve pressure. the piston could be cocked in the holder too.pinching the big oring seal. you cantry to pull piston out but use equal pull on both sides, i found rust on the piston just to the outside of the seal, this caused it not to retract also. cleaned it up with emery cloth.

You didn't by chance put in the heavy duty metalic brake disc did you. The 1066 came with them and I normally switched them to the regular lining discs to solve screeching poor holding problems. Some of the dealers push them when you buy linings. I'm not sure if they are even available these days though. Just a thought.
